I am doing some 3d printing and I would to show some my pieces,
but as they say, I would love to see some of the work you guys are doing first.
So post it right here in this gallery, and knows, maybe I can make a pitch to support more of this type of work in these parts.

I do a lot of 3D printing and 3D printer development. Unfortunately practically all the stuff i design, using Cinema 4D, is for technical purposes.
Usually i create a polygon model not only for printing but also for preview renderings of functions and for collision detection etc.
Some stuff can be found here:

One simple but nice thing i designed and printed is this keychain
I just got into 3d printing this month, so I don’t really have much. I did start to print some test peices of an ABS filter ring for my Tokina 10-17 fisheye lens. Its meant to cover up the edges of the lens hood so that when you place a filter or adapter on the 58mm threaded hood, there’s no light leakage. I plan on glueing a 58-72mm step ring to the printed ring, for 72mm filters. I’ve also been messing with a version that has threads, so I wouldn’t need the step ring, but the printing tolerances are proving tricky. Also when I have everything perfect I’ll probably get some black ABS.

Been playing with 3D printing for a few months now, and bought my own printer too. Here’s just a few of the recent tests I’ve been running.
Also on my blog http://arddigital.co.uk/blog/ there’s some more in depth posts about my prints.
Man I’m jealous. It all looks cools fellas, from the technical to the artistic.
Making practical items virtually for real world use, love it.
Which reminds me of this handy thing i designed
http://www.thingiverse.com/thing:38984
An adapter to put a 2 1/2" SSD into an old style MacPro
Due to the way most common adapters are build they don’t work with the Macs locking sliders. I originally designed it for some of our developers that wanted to speed up their development systems, but i think many artists would like to speed up their rigs as well.
had some fairly good results using shapeways
their metal printing is pretty cool, they print a wax one and make a cast iirc
Well for my adapter ring, I was able to print threads so that a filter will screw right into the ring. The fit is a little tight, so I mights adjust the tolerances to something like 0.05mm more, which has already been adjusted to a whole 0.25mm, so that would end up being 0.3mm, which I figured I would have to make some adjustments with extruded ABS. From what I’ve researched, ABS can require anything from 0.1mm to 0.5mm in tolerance adjustments, depending on the printer / filament. Man I can’t wait to get some black and maybe some red ABS.
I would like to start messing around with acetone smoothing for ABS, which I believe can help to reduce the need for for larger tolerances. Does anyone here have any experience with acetone smoothing? The vapor smoothing looks pretty involved and dangerous. I’ve seen that you can dip parts in acetone for a few seconds and then let them air dry. I was considering trying to find a bottle that I can spray parts with, which might yield good results, the problem is in finding a sprayer that wouldn’t be damaged by the acetone itself.
BTW I definitely think a gallery would be would be great. What would also be great is a WIP section for 3D printing, to maybe see the progress on complicated or even basic projects.

Don’t bother with immersion, it will not work as you expect. The best results so far i got using hot vapor. Depending on the item you can get a smooth finish as if it were injection molded.
Sorry for the crappy iPad shots

Does anyone have a Form 1+ printer? I have been looking at printers trying to decide which one to get and that seems to be the best of the bunch as far as quality goes.
I agree with the immersion not working, but I also think hot vapour isn’t brilliant either, unless you have a real complex setup where you use fans to evenly distribute the vapour.
I find cold vapour to be much easier, and gives better results, but does take longer. Acetone by its nature will vaporise at room temp, so by putting your print into a closed container, the vapour will work, but as I say, it can take hours to see the results.
Anyway I’m always testing and playing with this kinda thing, check out my instagram if you’re interested http://instagram.com/punch_ard_digital

That was actually my biggest problem with cold vapor. With hot vapor it takes only minutes, if that, so you can just watch and terminate at the moment it is to your liking. If you expose things for to long the whole object will become soft and deform.
Did you find much problems with taller pieces, like the bottom “melting” more than the top?
Yeah from what I’ve heard the results aren’t as good. I would still think you could spray a few light mists of acetone on the print from a bottle, let it air dry and it would turn out decent. I did see a video yesterday of someone using an aerosol can with an acetone base that was meant for cleaning / degreasing for smoothing, but of course I can’t find it now, and I forgot the brand. Looking on amazon, I did find these -

That cold vapor method sounds interesting. How many hours does it take with that? At least you could maybe set a timer. Maybe you could spray the print very lightly before the cold vapor method to speed up the process,. or you could maybe set the jar under some warm lights. From what I’ve seen, taller pieces are indeed more problematic with vapor methods, because of the vapor having to rise. You might have to somehow suspend the print upside down and lightly smooth it.
Besides acetone I’ve also heard that you could use a heat gun for smoothing,
I would say the B9 is better, the Form1 print settings are very poor, along with their materials. People have done lots of different tests with materials and there’s some amazing results there. The new one also has a higher resolution projector than before so it can print even higher detail and smaller objects. The only downsides of the B9 is the build volume at higher resolutions, and the PDMS coating on the bottom of the vat which has to be replaced from time to time(a bit more often than you’d like).
I find just leaving it for a few hours works well. If you open a bottle of acetone (or as I use, nail polish remover), you can immediately smell the vapour. I use glass jars and bowls so I can see how it’s doing.
Also to speed things up, you can add wicks, like tissue paper lined up the inside of the jars, which draw the acetone up, without it touching the print.
Speed isn’t everything.
That is really cool Rob. At first I couldn’t believe you got all those colors in a print and then… oh yeah, painting, you can do that. 
How durable are those tiny lattices?
I am doing mini figures proposals for work.
Here are some of the work I have done so far.
